Will It Take Off?

There’s been a little bit of a conversation on this matter, and I’m not sure why. It seems obvious to me, right?

    Why would it take off? The wheels would spin, but no lift is created.

    No you idiot, it does take off. Haven’t you ever seen an airplane take off at an airport? It has to go fast in order for that to happen. GOSH!

    I think it would take off, because when your on a treadmill you’re techincally moving. just doesnt seem like it.

    In any even if it did the wings would break on the side of the treadmill and it would crash anyways lol.

    This may be fun!

    It will of course take off, even assuming the treadmill is the size of a real landing strip (which is part of the original supposition).

    The wheels do not move the plane, nor create lift. They are incidental to the aircraft’s takeoff. The propellers or jet engines create the forward force. Other than spinning madly (or not moving at all, depending on how the question is worded), it will have no effect on the takeoff, which would occur normally.

    Why would the wings break off? It would actually go away from the control panel. Maybe, if you turned the plane around and gave a little more incline (away from the control panel), you’d get a bit of distance.

    because it has to go forward and it can’t go up like a helicopter. So if it goes forward the wings would break because the wing span is larger than the treadmill.

    No. How would the wheels spinning create the wind resistance needed to lift the plane?

    How is that debatable? It’s not that the plane goes fast enough that it suddenly by magic can fly. It’s the wind pushing on the wings that causes the lift.

    Kero, why would it go forward? Do you run backwards on the treadmill? No. See the video or animated GIF of the girl busting her ass on a treadmill. NOTE: she doesn’t go forward, her legs don’t break off, BUT it IS damn funny.

    Actualy this is a good thing to ponder about.
    IMO

    The plane would take off as from a normal runway.
    The thing is is that the airplane is using air around it to drive itself, not the wheels.

    It would just take off ignoring the treadmill completeley.

    On the other hand, if you make a treadmill from air (think lots of stacked together fans) you can get it to “Hover” in place O_o.

    I don’t get the debate; how could it possibly be able to take off? Assuming it could get enough propulsion to counteract the motion of the treadmill, it still wouldn’t be able to take off since the treadmill isn’t nearly long enough for the plane to be able to accellerate enough to generate lift. And assuming it somehow would be able to, it would either have to instantly tilt upwards at almost a 90 degree angle in order to clear the control panel and stand, or rotate dramatically along the chassis to avoid having the wings completely sheared off.

    It won’t take off. Anyone who remembers the least bit of Physics could tell you why. Lift is created by a pressure differetial between the top and bottom of the wing, created by the difference in length of travel of air over the wing. It’s called Bernouli’s Priciple. Since in this case, there would be little to no airflow over the wings, no lift would be created. The wheels can spin all damn day, and if there’s no lift, no takeoff. The whole purpose of wheels on a plane is to reduce friction between the ground and plane, making it… Read more »

    Ok. Imagine you have a hypothetical 2 miles long treadmill. If the engines are set to full power the plane will simply push itself using the air around it(Thats how a jet engine works). The wheels will spin madly (due to speed relative to the earth+speed of the treadmill). However the engines and the lift generation component ignores the treadmill speed nearly completely. (the plane might be set a few hundred feet back at the start while spooling up the engines). Given the fact that the wheels are there just to reduce friction (and they DO that, the plane wont… Read more »

    Wait no it doesnt. Assuming the wheels don’t break off because they would be skidding the plane would take off. Because the the jets that move the plane not the wheels. so the plane would go forward and the wheels would just skid across it and kind of break, and then the plane would crash. But if the wheels were hylothetically indistructable, then the plane would take off.

    another thing to take into consideration is the immense thrust that is being shot out the back of the turbines, I dont know how much thrust exactly but i do know that the engines on full power, if left stationary for too long will eventually start ripping up the runway.. they are pretty damn powerful and this idea would just screw up the runway

    pete
    Guest

    Your answer would be correct if the forward thrust of the plane were being created by the wheels. Since the wheels are free spinning, and the thrust is being created by the engines, theoretically the plane can take off. Assuming that the treadmill was long enough, and that the thrust of the plane could overcome the extra resistance that would be put to the spinning wheels. That is of course assuming that the wheels can withstand the extreme spinning that would occur. An example would be if the tread was spinning at 12kph, and the plane tries to head forward… Read more »

    If we’re going out on limbs here, then yes, if you had a treadmill 1-2 miles long, and you had enough forward thrust to overcome the treadmill speed and still get enough forward air speed for the lift required for takeoff, then you could get this beast off the ground. If you’re going to build a 2 mile long treadmill for this experiment, here’s a question… Why not just build a damn runway? It seems that whole posit is if you could somehow get it off the ground on an abbrevated runway using a treadmill or like device. I say… Read more »

    Umm, so the answer to this puzzle depends on the exact wording of the question. I’ve seen it written two ways, and I’ve answered each below. 1) If the treadmill were designed to match the speed of the PLANE, it will take off. Say the plane is traveling at 100 mph (relative to the GROUND), then the treadmill will spin at 100 mph in the opposite direction, causing the wheels to spin at 200 mph. The wheel speed does not match the plane speed (or the treadmill speed); however, the plane is moving relative to the ground (and air–no magic… Read more »

    Two scenarios.

    1. no take off – the plane does not move forward due to the force of the treadmill against the wheels. this is not how plane wheels work, however.

    2. take off – the plane takes off because even though the wheels spin madly, they have no bearing on the engines pushing the plane forward.

    It seems to me the essential question is “Can a plane take off (lift off) without moving forward (staying in place). Not with a treadmill. Maybe with a large fan blowing air over the wings… What if the wings moved by themselves, say, rotating around a central axis, thus generating air resistance that generates lift! Yeah, that would work! I think we should call this new idea “Helicopter”. Wait a second! There’s another way for this to work. If the jet engines actually swiveled to produce vertical thrust… it would be a feature that we could call “Vertical Take-Off Landing”,… Read more »

    People are getting quite vehement without realising that their opponents are answering a different question to them. There are two different questions here, and that is what is causing the confusion. Q1. Can use of a treadmill allow a plane to take off without moving forward? To which the answer, is, of course, no. You’d get no airspeed under and over the wings, hence no lift. Q2. Can a plane take off if there is a treadmill under the wheels, spinning in the opposite direction to the planes movement, set to match the speed of the planes forward motion? (This… Read more »

    Well… The engines push the plane and the air resistance against the wings causes the lift. Without the resistance generated by the motion of the plane the efforts of the engines are for nothing. Regardless of the size of the phantom treadmill or railings the plane would not take off. The concept contradicts the physics of flight. Your implying that the plane would move along the treadmill because the wheels are there only to hold it up until the necessary air pressure is there. For your scenario to work the plane would need to go faster than the treadmill could… Read more »

    ok… Imagine a treadmill that’s long enough for a plane to take off of. When the treadmill starts to move back, the plane will also start to move back. In order to stay in place, the plane will have to push itself forward. How do planes push forward? By pushing air back. The faster the treadmill moves, the faster the plane engine will have to push air backwards. This creates a RELATIVE motion of air over the wings. “Everybody stand up and run in place, as though on a treadmill. Feel any wind?” [comment 24] Of course not… you’re moving… Read more »

    I can’t believe this is still an issue. Of course the treadmill will take of, its got an airplane pushing it! Seriously, the plane would never leave the ground due to no air going across the wings, creating lift, which is how a plane flies, not by “Pushing air back.”

    The people who say it will not take off wrongly assume that acceleration is in the wheels. Based off their assumption, if the wheels push the plane forward at 200 mph, and the treadmill moves back 200 mph, then the AIRSPEED will be 0 mph and the plane will obviously NOT take off. TREADMILLS DO NOT PUSH AIR! However that is a wrong assumption. The acceleration is in the jet propulsion, which is dependent on conservation of momentum, not tires. If the plane is being thrust forward 200 mph and the ground is moving back 200 mph, the ground speed… Read more »

    Addendum:

    If the treadmill goes from 0-200 mph in 0.1 seconds, and you are sitting in a car in neutral, your wheels will spin but you won’t really move too much (assume everything stays intact).

    It’s like pulling a tablecloth from under a marble.

    If you have a jet engine on your car, it will start pushing your car forward, while your wheels are still spinning like crazy.

    That is the correct way to model it, because at high speeds friction of the treadmill on wheels is negligible.

    How does a plane move? Force caused by it’s engines. The wheels have nothing to do with it. If they did, how would a water plane take off?

    Think of it as if you replaced the wheels with skis. The plane would still take off just fine on a normal run way. On the treadmill, sure, the treadmill will spin the wheels backwards at some X speed, but the plane will still move forward regardless.

    Hmmm….i’m a pilot and i can say this…. an fixed wing aircraft will only take off if and only if there exist sufficent air movement (wind) aross the wing (thats what a wing does; it converts wind energy into lifting energy). A plane on a moving treadmill do not receive any wind for it to take off.

    to Aristoi on Dec 15th,

    The engine does provide a small portion of lifting power. If you know anyting about vectors, you will notice that a componet from the engine’s power is pointed upwards, hence lift. However, this is only true when the engine is pointed above the horizon.

    To those cares about the wheels!!!!!!

    IT DOESNT MATTER WHAT THE WHEELS ARE DOING… Some planes dont have wheels –> flat planes and ski planes. Wind and wing is all that matters when it comes to take off. A plane can still take off if there is enough headwind even if the plane is stationary… try it on flight sim.

    It won’t fly. I don’t see how this is even a serious question.

    The wheels will turn, but that doesn’t mean anything. What makes it fly is the lift created under the wing.

    And in order to do that it has to be actually moving through the air. On a treadmill the plane will be motionless, regardless of the wheels, and the air will therefor not generate lift.

    Apparently this is not the first time its been pointed out, which brings me to my next point:

    WTF IS THIS STILL DOING AT 1# MOST COMMENTED???

    This will not work because the only way the plane gets off the ground is by air resistance.

    #2, the treadmill goes backwards. Even assuming that the jet’s engines are going fast enough to take off if the jet were on the ground, there is no wind for the wings to push off of to get lift off of the ground.
